ter referred to, and mounted in a step M and Motion is transmitted fromthe thrashingmachine with which the stacker is used, or from any othersource, to the carrier through .a shaft w, mounted in the boxes y y,secured to the general frame, and having a sprocketwheel a and abevel-pinion b, which meshes with a similar pinion c on the shaft L,already referred to. The upper end of this shaft L is provided withanother bevel-pinion cZ, which meshes with a similar pinion e, carriedby a shaft f, (shown in dotted lines in Fig. 8,) and mounted in pendantsg, extending from the sill 0, one of which is seen in Fig. 8. This shaftf carries a sprocketpulley 72., which is connected by a sprocketchain 1"with the carrier-driving shaft 7" through a sprocket-pulley k. It willbe observed that the power is transmitted from a shaft mounted upon thestationary frame to the carrier through a vertical shaft, whichconstitutes the pivotal bolt for the swinging operation of the stacker.

I will now refer to the mechanism for giving motion to the master-wheel,which I term the swinging mechanism. This consists of .a shaft Z,mounted in suitable boxes secured to a standard Z on the main frame, andcarrying a worm 0, which meshes with wormgear teeth formed in aboutone-half of the periphery of the master-wheel. This shaft carries twopulleys p and g, which receive motion in a manner presently to appear.They are loosely mounted on this shaft, and are clutched therewith by adouble-faced clutch 1", also mounted on the shaft Z, with aspline orfeather key to rotatably connect it with the shaft. The pulley p rotatesin one direction and the pulley q in the other direction, so that whenone of these pulleys is clutched to the shaft Z the master-wheel throughthe worm 0 is rotated in one direction and the carrier-frame swung toone side say to the left-as viewed from the front end of the machine,and when the other pulley is clutched to said shaft the master-wheel isrotated in the other direction and the carrierframe correspondinglyswung in that direction. The means for alternately clutching thesepulleys p and q to the shaft Z consists of a sliding shifter-shaft s,mounted in suitable bearings 6, carried by the standard Z, having an armto, which engages with the clutch r. A trip, consisting of an arm to,pivoted to the piece m by its bolt m is connected with the shifter-shafts and arranged to be struck by strikers, hereinafter de-' scribed, andcarried by the swinging mechanism, so as to shift the clutch fromengagement with one of the pulleys at about the limit of the swing intoengagement with the other of the pulleysp and q, so as to reverse thedirection of rotation of the shaft Z, and hence rotate the master-wheelback in the other direction, at the limit of which another strikeractuates the arm w and throws the clutch into engagement with the otheror first engaged of said pulleys.

In Figs. 4 and 5 I have shown a modification of the tripping devices,consisting of a bar 'y, pivoted on the pivotbolt of the arm w, andhaving projections z and a weighted upper end. The projections z arefirst met by the strikers above referred to, and the bar 1 given athrust to one side, so that this heavy upper end will acquire sufficientmomentum to throw the arm w by engaging it with one of said projectionsfar enough to insure the required movement of the doublefaced clutch r.This latter form of trip is preferred, because with it the clutch issure to be moved the proper distance.

Referring now to the strikers, these consist of the slotted bars 2, adjustably'secured by the thumb-nuts 3 to the ends of the sill O, andhaving lateral extensions 4, which engage with the trip devices alreadydescribed. The object of making the strikers adjustable is to cause themto strike the tripping device sooner or later in the swing of thecarrier, so as to determine the limit of such swing.-

I will now refer to the mechanism for giving motion to the pulleys p andg. This consists of a shaft 5, mounted on the rear end of the mainframe, and having pulleys 6 and 7, which are connected with the pulleysp and g, respectively, by a crossed belt 8 and a straight belt 9, so asto rotate said pulleys in opposite directions. A sprocket-wheel'lO isalso carried by the shaft 5 and receives motion through a sprocket-chain11 from a sprocket-pulley 12, carried by the shaft w.

' It will now be observed that my improved machine comprehends arotatable masterwheel carrying a ,superincumbent carrierframe, with itshopper and endless carrier proper, elevating mechanism for the carrier,adjusting mechanism for the carrier, and a portion of the drivingmechanism for the carrier, and the remainder of the power-transmittingmechanism upon the main frame,:together with the power-transmittingdevice for the swinging mechanism and the shifting devices therefor.

As thus constructed, all of the various adjustments as to position, theextent of the swinging of the carrier, the application of the power fordriving and swinging the carrier, and automatically changing the direction of the swinging, as Well as a proper balancing of the machine, areall provided with simplicity in the construction of the various parts.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a straw-stacker, the combination, with the main frame, a circulartrack, one or more supporting-rollers, and a supporting-bracket having aroller engaging said track, of a inaster-wheel mounted upon said trackcarrying said bracket and supported by said rollers, motion transmittingmechanism including a worm geared to said master wheel, a carrierframe,its hopper, and a carrier proper in-' cumbent upon said wheel, pivotedlevers, a
